To all whom it may concern,.-

Beit known that we, J osEPH LEMPEREUR and LAMBERT BERNARD, of Liege, in the Kingdom of Belgium, have invented certain new and useful Improvementsin Lamp-Burners, of which the following is a specication.

This invention relates to an improved lampburner, by which a perfect combustion of the oil and a clear and white flame are obtained; and the invention consists, first, of a deiiector having a lower perforated disk and a button above the same; secondly, of animproved device for locking the gallery and the outer wick-tube to the collar of the bowl, as will be described more fully hereinafter, and finally be pointed out in the claims. l

In the accompanying drawings, Figure 1 l represents a side elevation of my improved lamp-burner shown as applied to alamp-bowl. Fig. 2 is a vertical transverse section on line y y, Fig. 1, of the burner and bowl, drawn on a larger scale. Fig. 2 are detail views of the detlector. Fig. 3 is a side elevation of the wick-tubedetached; and Fig. 4, a horizontal section on line xx, Fig. 2.

Similar letters of reference indicate corresponding parts. 4

Referring to the drawings, A represents the bowl, which is provided with acentral draftopening, a, and an inner wick-tube, B, that is permanently secured to the bottom of the bowl. The bowl has to be supported in such a manner on the table or other support that the air can pass freely along the bottom of the bowl to the central draft-opening and inner wick-tube, B, of the same.

At the upper part of the fixed wick-tube B is supported by radial arms a central socket, b, that carries avertical central pin, b', to which is applied the tubular shank, b2, of adetlector, C, which consists of a lower disk, d, having perforations d2, and of an upper disk-shaped button, d', of a smaller diameter than thelower disk, d, which button is connected by an outwardlycurved shank, d3, with the disk d. The current of air that is drawn up through the inner wick-tube, B, of the bowl A is divided by the defiector into two currents, one being deflected toward the base of the flame, while the other is passed through the holes of the disk d, heated in its passage through said holes, and deiiected by the curved surface of the shank of the disk in upward direction toward the upper partof the iiame, as indicated by arrows in Fig. 2. This produces the perfect combustion of the gases at the base and upper part of the flame, so that a clear white flame is obtained. The chimney is made bulging above the delector, so that a iiame in the shape of a tulip is obtained, as shown in Fig. l. The flame is contracted again somewhat at the upper end, so as not to strike the chimney directly, and renders it therebylessliable to cracking. The chimney is supported by a gallery, D", on raised rests e ofthe basket D, so that the air can pass around the lower part ofthe chimney and through holes eintermediately between the rests e to the inside of the dome D'. The lower part of the basket is perforated, so as to supply the required quantity of air to be drawn into the dome D', and thence to the outer surface of the flame.

The basket D is provided at its base with a ring-shaped collar, f, that ts around a collar, f', of the outer wicktube, B', said collar f being provided on its interior with a groove, f6. The collar f' of the lamp is provided at diametrically-opposite points with L-shaped slots f2, which are engaged by inwardly-bent end lugs of a semicircular bail, f 3, which slides in the groove f of the collar f,lbetween said collar and the collar f'. The bail f3 is provided with a txed button, f4, the shank of which is guided in a slot, f5, of the collarf at the base ofthe basket D. By taking hold of the button f4 and moving it in one direction the bail f3 is moved to one side in the collar f, so that its end lugs clear the slots f2 of the collar f' of the wick-tube B', and that the basket D may be detached from the wick-tube B', together with the chimieyand without requiring the removal of the latter. By placing the collarf of the basket D in position on the collar f' of the outer wick-tube, B', inserting the end lugs of the bail j"3 into the upwardly-extending ends of the L-shaped slots f2, and moving the button f 4 and bail f3 sidewise, the end lugs of the bail engage the horizontal portions ofthe slots f 2, and lock thereby the basket D rigidly to the outer wick-tube, B', as shown in Fig. 4.

To facilitate the raising and lowering of the wick E, a wick-carrying tube, F, is arranged in the outer wick-tube, B', the tube being provided, preferably, with three springs, g, that are attached at the lower end to the tube F and bent inwardly at the free upper ends. The bent upper ends of the spring g pass through slots g of the tube F and are toothed, so as to engage the wick, as shown in Fig'. 4. The lower end of the wick-carrying tube F is attached to a vertical rack, h, that is guided in a recess of the collar f of the outer wick tube, B. The rack h is raised or lowered by a pinion, h', of a shaft, G, that turns in bearings ofthe collar f of the outer wick-tube, and serves to set the wick higher or lower by raising or lowering the rack and the wickcarrying tube. The springs g are held in engagement with the wick by the outer wiektube, B. When the wick-carrying tube F is lowered until the upper ends ofthe springs g are in line with radial recesses gz at the inside' of the collarf of the wick-tube B', the upper ends of the springs g spring outwardly into the recesses gz, so as to release the wick when it is desired to readj ust the same in the wickcarryingtube or insert a new wick. By raising the wick-carrying tube F again by turning the handle of the shaft G the upper bent ends of the springs g are raised above the ra- -dial recesses g2, and are pressed by contact with the outer wick-tube, B', into the wick,

so as to re-en gage the same, as shown in Fig. 2.

The bowl A is provided with an opening for filling the same, said opening being closed by la shoulder, i', at the lower part.

a screw-plug, H, which has a vent-hole, i, and

The shoulder i forms a seat for a valve, i, which is pressed by a spiral spring, i3, against the shoulder i. W'hen the pressure of the gases overcomes the tension of the spiral spring i3, the valve i2 is lifted, so that the gases in the bowl can escape, whereby danger of explosion is avoided. Y

Our improved lampburner has the following advantages: Perfect combustion of the oil and aclear and white dame, convenient and reliable locking of the basket to the outer wick-tube Without removing the chimney, and the convenient and reliable inserting and readjustment of the wick in the wick-tube.

Having thus described our invention, we

claim as new and desire to secure .by Letters Patent- 1. The combination,with au Argand burner, of a deflector comprising a lower disk having perforations and a smaller disk-shaped button above the lower disk, substantially as de" a button the shank of which is guided in the slot of said basket-collar, and with bent end lugs for locking the basket to the slotted collar of the wick-tube, substantially as described.

,4. The ecmbination,with an Argand burner,

of the outer wick-tube having a collar providedY Y with radial recesses at the inside, a wickcar rying tube having springs with inwardly-bent and toothed upper ends passing through slots of the wick-carrying tube, a vertical rack attached to the lower end of the wick-carrying tube, and apinion-shaft for operatingthe wickcarrying tube, substantially as described.

5. Thecombination,with an Argaud burner, of a lamp-bowl having a cylindrical passage and Xed wicktube, an outer wick-tube having a collar with radial recesses at its inner side, a wick-carrying tube having slots near its upper end, wick-holding springs attached at their lower ends to the wick-carrying tube, and having bent and serrated upper ends, a rack attached to the lower end of the wickcarrying tube, and a shaft having a pinion
